I cannot figure out why the bulk schedule publish operation fails intermittently with a 500 Internal Server Error when using the postWfmSchedulingSchedulesPublish endpoint. This issue appears specifically when processing large volumes of shift assignments for our Chicago-based support tier. The workflow involves calculating optimal shifts based on agent preferences and shift swap approvals, then pushing the final schedule via the API to ensure strict adherence to our weekly publishing SLA.
The request payload includes approximately 450 agent assignments spanning a two-week horizon. The API call succeeds roughly 60% of the time, but the remaining 40% trigger an immediate 500 error with no detailed error message in the response body. The SDK logs show the request is valid and authenticated correctly, as confirmed by successful test calls with smaller payloads (under 50 assignments). The error response structure is minimal, lacking the specific constraint violation details usually seen with 422 errors.
We have verified that all agent availability, skill group assignments, and time-off requests are synchronized and conflict-free prior to the publish attempt. The issue persists regardless of whether the schedule is published via the UI or the API, though the frequency seems higher with programmatic calls. This inconsistency disrupts our automated scheduling pipeline and forces manual intervention to retry failed batches.
Has anyone encountered similar instability with bulk publish operations in the WEM API? Are there known limitations or best practices for handling large payloads in this endpoint that we might be missing? Any insights into debugging 500 errors with opaque responses would be greatly appreciated.
